||||||||||Efficacy of Anti-Allergen Therapeutics in a Preclinical Model of Allergic Anaphylaxis Correlates with Symptomatic Relief in Allergic Patients () - Apr 30, 2022 - Abstract #EAACI2022EAACI_998; Blockade of individual mAbs versus mAb cocktails confirms optimal blocking efficacy of Fel d 1 mAb cocktail (REGN1908-1909) compared with either single mAb; Bet v 1 triple mAb cocktail (REGN5713-5714-5715) compared with single mAb (REGN5715) or dual mAb cocktail (REGN5713-5715). Conclusion Blockade of mast cell degranulation in the PCA mouse model correlates to efficacy in clinical settings, validating the model as a useful tool for selection of efficacious anti-allergen therapeutics.
